TrawlEye Mode function
Depending on your operational needs or on the properties of your PX TrawlEye, you can choose how to see your echogram. If the PX TrawlEye is equipped with a Depth Lid and the depth measurement is enabled, you can also select to view the PX TrawlEye echogram in true motion.

Description
The TV80 shows the echograms provided by the PX TrawlEye sensor.
Details
Fixed headrope
The echogram will work in the area defined between where the TrawlEye is placed and the selected range.
If your TrawlEye sensor is configured for Dual Range, Fixed Headrope has two different values between brackets. With dual range, 50% of the echogram resolution is used on the first 5, 10, 15 or 20 meters; the rest of the resolution is used on the rest of the echogram: that is 95, 90, 85 or 80 meters.
True Motion
In True Motion mode you can gradually see how deep your sensor is falling. True Motion is especially important in bottom trawling since you can visualize how the headrope - where the sensor is mounted- increases depth in real time. When the TrawlEye sensor is mounted on the trawl doors, the True Motion mode is also a valuable tool for some fisheries to see in detail, and with fast update rate, how doors approach the bottom and how far from it they are.
